When an acid dissociates, the conjugate base ends up with a negative charge. The better the base is able to stabilise this charge, more of the acid is dissociated at equilibrium, the acid is stronger.
The phenyl ring can resonance stabilise this charge around the ring, the charge is said to spend some of its time on the ortho and para carbons, so the charge is less localised to the oxygen.

Which is stronger acid ethanol or phenol?
Phenol is stronger acid than ethanol. Phenol's acidic strength stems from the presence of the -OH group attached directly to the aromatic ring, which allows it to readily donate a proton. Ethanol, in contrast, has a less acidic -OH group due to its aliphatic structure.
Why phenol is stronger acid than ethanol?
Phenol is a stronger acid than ethanol because the phenoxide ion formed after losing a proton is stabilized by resonance, making it more stable. In contrast, ethanol forms a less stable ethoxide ion due to the lack of resonance stabilization. This difference in stability influences the ease with which the acids donate a proton.
Is 1-hexanol more acidic or less acidic than phenol?
Phenol is more acidic than 1-hexanol because the hydroxyl group in phenol is directly attached to the aromatic ring, which stabilizes the resulting phenoxide ion through resonance. In contrast, the hydroxyl group in 1-hexanol is attached to an aliphatic chain, making it less acidic.
What is more stronger acetic acid or ethanol?
Acetic acid is a stronger acid. Ethanol is an alcohol which is slightly acidic but usually neutral in nature.
Can you get phenol from carbolic acid?
Phenol and carbolic acid are actually the same compound. "Carbolic acid" is an older, colloquial term for phenol.

In contrast, ethanol forms a less stable ethoxide ion due to the lack of resonance stabilization. This difference in stability influences the ease with which the acids donate a proton.
Which is stronger acid aromatic or aliphatic?
Aromatic acids are generally stronger than aliphatic acids due to the resonance stabilization provided by the delocalization of electrons in the aromatic ring. This makes the aromatic acids more stable when releasing a proton, resulting in a stronger acid.
How to convert phenol to aspring?
Phenol is converted to aspirin by adding carboxylic acid and esterifying the alcohol.
Which is strong acid water or phenol?
A strong acid is typically stronger than phenol in terms of acidity due to its ability to fully dissociate in water to release protons. Phenol is a weak acid that only partially dissociates in water, making it less acidic compared to strong acids like hydrochloric acid or sulfuric acid.
Is 1-hexanol more acidic or less acidic than phenol?
Phenol is more acidic than 1-hexanol because the hydroxyl group in phenol is directly attached to the aromatic ring, which stabilizes the resulting phenoxide ion through resonance. In contrast, the hydroxyl group in 1-hexanol is attached to an aliphatic chain, making it less acidic.
Give four properties of phenol to show how it differ from alcohol?
1-Phenol (carbolic acid) is acidic in nature and turns blue litmus red while alcohol (ethanol) does not, 2-phenol gives violet or blue colour with neutral ferric chloride solution while alcohol does not, 3-phenol freezes to a solid in fridge while alcohol does not, 4-phenol produces bubbles on rough iron surface while alcohol does not.
What is more stronger acetic acid or ethanol?
Acetic acid is a stronger acid. Ethanol is an alcohol which is slightly acidic but usually neutral in nature.

Why is aliphatic amines stronger bases than aromatic amines?
Aliphatic amines are stronger bases than aromatic amines because the lone pair on the nitrogen atom in aliphatic amines is more available for donation due to the absence of resonance effects that stabilize the lone pair in aromatic amines. This makes aliphatic amines more likely to accept protons and act as bases.
Which is a stronger acid cresol or phenol?
Phenol is more acidic because cresol has +I effect of CH3 grup as you know acidity is reciprocal of +I effect. OR Cresol has electron donating methyl group, whih reduces its electron defficiency of the phenol group and hence acidity.
Is phenol a base?
No, and it is neither an alcohol (OH) but it is a very weak ACID!C6H5OH --> H+ + C6H5O- (fenolate anion) pKa=9.89
